LFA 447 NanoFlash®

Determination of thermophysical properties is quick, easy and cost-effective with the new LFA 447 NanoFlash® Light Flash System.

A high-performance Xenon flash lamp takes the place of the laser, which is usually employed for this proven technique.

With the integrated sample changer for 4 samples, it is possible to run measurements on several samples automatically. The easily-accessible sample carrier allows short setting periods for test preparation and a high through-put of samples.

Unique is the optional scanning device (MTX) for flat samples up to 50 mm x 50 mm for determining differences in the thermal diffusivity over the entire sample surface with a spatial resolution of 100 µm in the x and y directions.

Features

  • Accurate pulse length correction
  • Heat-loss corrections, all literature models are integrated
  • Non-linear regression for Cowan fit
  • Improved Cape-Lehmann model through consideration of multi-dimensional heat loss and non-linear regression
  • Radiation correction for semi-transparent samples
  • 2- or 3-layers systems: analysis by means of non-linear regression and consideration of heat loss
  • Determination of contact resistance in multi-layer systems
  • Model wizard for selecting the optimum evaluation model
  • Determination of specific heat by means of a comparative method and standard samples
  • Integrated databank

I'm having an issue with the 447 not connecting in the Nano Flash software. Checked the com port and it is functioning, however when i run the Nano Flash software I receive Communications with hardware failed. Any thoughts?

Working of LFA 447 NanoFlash for a Two Layer Sample

I am working on thermal diffusivites of Zirconia which is deposited on Stainless Steel. I wanted to know how exactly the machine works for a two layer sample. For substrate I am using Cowan method and for the coating of Zirconia 2l heatloss model.
